SIDE THRUST SUPPORT non SPRING BED Borroms.

Application led January 29, 1923. Serial No. 615,523.

i This invention relates to a side thrust support for spring bed bottoms and has special.

reference to that class of supports disclosed in our Patent N o. 1,415,068, granted May 9, 1922, in which we show a conventional `form of bed spring bottom having upper and lower frames with interposed springs and said frames are connected by means maintaining a defined 'relation between said frames, particularly to limit the upward and inwardmovement of the marginal edges of. the top frame relative to the lower fra-me. Such means is employed to prevent excessive pressure centrally of the spring bed bottom from distorting the marginal edge of the top :trame without materially interfering with the yielding ofthe springs in the usual manner. In other words, the to frame work orywebbing of the spring be bottom is maintained stretched and taut without any central portion thereof being sagged or.

depressed due to constantuse. n

Our invention aims to provide side thrust supports each consisting of props, links or members articulated to resist and limit the upward arid'inward movement of the top frame of the spring bed bottom, besides deinin'g the lowering movement ofthe top frame should the marginaled es thereofjbe depressed. This is accomp ished by a simple, durable and inexpensive construction and since a plurality of supports are embodied in each spring bed bottom, any improvement which reduces the number of support parts, standardizes such parts or simplifies thev construction and manner of assembling the parts will produce a large saving when such sprin bed bottoms are extensively manufacturer?.

Reference will now be had to the drawings,

Figure 1 is a diagrammatic plan of a spring bed bottom in accordance with our invention; n

Fig. 2 is a side elevation of a three link side thrust support;

Fig. 3 is a similarview of a two linkside thrust support.

`As y illustrating a conventional form of spring bed bottom, we show a lower frame l and the side rails2 of this'frame are connected by transverse spring supporting membersr on which are mounted and suitably securedthe lower convolutions of f springs 4, said springs having thel upper convolutions thereof within an upper frame 6 which is held in spaced relation to the lower frame 1 by the springs 4. The spring supporting members 3 may be conveniently considered as being in sets with the members of each set connected by longitudinally disposed bars 7 and each bar, intermediate its ends, is connected tothe rail 2 by an inclined base piece 8 having its ends bentl or twisted for attachment `to the rail 2 and the bar 7 by rivet or other fastening means.

Reference will now be had to Fig. 2 wherein the inner end of the base piece 8 has a fixed and rigid upright 17 to which the in'- ner end of the frame link 11- is connected, by a pin and'slot connection. The frame link 11 has its inner end longitudinally slotted, as at 23, to .receive a stud orfpin 24 of the upright 17, and the lower end 25 of said upright extends below the base piece 8. Pivotally connected to the intermediate portion of the frame link 11 is a connecting link 26 which is also pivotallyconnected to the base piece 8 with the lower end of the connecting link connected by a coiled retractile spring 27 to the lower' end 25 of the upright 17. An outstruck stop lug 28 of the frame link 11 defines the angular relation of the links 11 and 26. y l y In Fig. 3 the base piece 8 has 'a longitudinal slot 34 for a pm or stud 35 of the frame link 11 and said frame link` has its intermediate portion pivotally connected to a link 36 similar to the link 26. The lower end of the link 36 is connected -by a coiled retractile spring 37 to the lower edge of the base piece 8, which is cut away to provide clearance for said spring. The action of this ,last arrangement of links is somewhat similar to that shown -in Fig. 2, withv as` v the exception that the inner lower endl of the frame-link 11 is at all times held bythe base piece 8 to shift longitudinally thereof. In all of these forms of my invention the lower inner end of the base piece 8 may terminate in a tongue 38 clenched in an opening '39 of the bar 7.

1.111 a. bed Swing bottom wherein e0 and bottom framesl are held in superpose scope of the appen ed relation by springs between said frames i means for maintaining a defined relation between said frames, said means comprising units with each unit including a base piece, an inclined frame link liavin'g one end con- 'nected to the top frame ofthe bed spring 2. A bed spring bottom as called for inclaim 1, anda spring connecting said connecting link to the lower end of said upright. 4

3.V In a bed spring bottom wherein top and bottom frames are held in superposed relation by springs between said frames; means-for maintaining a defined relation between said frames, said means comprising units with each unit including a base piece, an inclined frame link havin'g one end con- 'nected to said inclined frame link and to 'nected to the top frame of the bed spring bottom, a connecting link pivotall)7- con'- u said base piece withthe lower end of said connecting link extending below lsaid base ieee, an upright on said base piece a spring mving one .end thereof held from said base piece and the opposite end of said spring. connected to the lower end of said connecting link so that the retractile force ofl said spring may cooperate with said connecting link in supporting said inclined frame link, and a pin and slot'conn'ection between ysaid 35 upright and said inclined frame link so Ythat the inner end of said inclined frame link will have a defined and limited movement',

relative to said base piece.

In testimony whereof we aix our signa- 40 tures.
